SPECIFICATION forming part of Letters Patent No. 487,777, dated December13, 1892.

Application filed July 25, 1892. Serial No. 441,194. No model.)

- exact description of the invention, such as will enable others skilledin the art to which it appertain's to make and use the same, referencebeing had to the accompanying drawings, and to the'letters of referencemarked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements intire-tighteners,'and aims to provide a device of this character whichshall be simple in construction and of easy application, whereby thetire of a car-,

riage-Wheel can be readily spread for the purpose of tightening thesame.

My invention consists, further,in the novel combination, arrangement,and adaptation of the parts, which will be more fully hereinafterdescribed, and then specificall ydefined in the appended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, like letters of reference indicating like partsthroughout the several views, in which Figure 1 is a side elevation of atire-tightener attached as for use on the wheel of a vehicle. Fig. 2 isa detail view of one of the guide-plates. Fig. is a detail view of asectional guide-plate through which passes'a threaded screw. Fig. 4 is asectional View taken on line x 00, Fig. 1.

Reference now being had to the drawings by letter, A represents thetelly of an ordinary carriage-Wheel; B, the spokes connected to thesame; 0, the hub, and D are clamps which are so constructed as to fitover the felly and are recessed, as seen at (Z, and said clamps areprovided with set-screwsE for securely holding the clamps to the feliywhile the tire is being tightened.

F are arms hinged to a guide-plateG at the pivotal pointf, and the endsof said arms are adapted to bear against the clamps in the recesses (Z.The guide-plate G has its ends bifurcated, so as to fit over the spokes,as shown at g H is a sectional guide-plate having the recesses at theend h, said sections being fastened together by means of pins or boltsI. Through the center of the plate H passes the bolt K, which isprovided with suitable nut and washer, and the end of said bolt isadapted to bear against the under side of the guideplate G, so that whenthe bolt is screwed up against the guide-plate the arms crowd the clampsagainst the felly, thus tightening the tire.

The simpleness of the construction of a tightener constructed inaccordance with my invention is readily seen, and the same can bereadily applied by any unexperienced persons.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

In a tire-tightener, in combination, having recessed tire-clamps, theguide-plate G, provided with arms pivoted near the center of the sameadapted to bear against the said clamps, of a secondaryguide-platefastened together with bolts, and a threaded bolt having suitable nutand washer, which passes through the sectional guide-plate and bearsagainst the guide-plate G, all substantially as shown and described.

In testimony whereof I my signature in presence of two witnesses.

JOHN P. ROSS.
